A look at the most-read articles in 2020 — regardless of publication date — reveals robust public interest in environmental health topics such as chemicals and consumer products, climate change, health conditions, the scientific endeavor, and not to be overlooked, COVID-19.
For the first time, the NIEHS Environmental Factor has seen one of its articles go viral.
Lavender oil makes the rank
In September 2019, we reported on an NIEHS study that linked compounds in lavender oil and tea tree oil with changes in the endocrine system. That piece has dominated traffic to the newsletter site ever since.
The pattern of monthly views of the lavender oil article indicates that its spread on social media built after initial publication (see chart).
Now, thanks to search engine algorithms that reward web pages receiving lots of traffic, “Lavender oil linked to early breast growth in girls” is the top-ranked result in a Google search for “‘lavender oil’ and girls.” That ranking then encourages more clicks, in a positive feedback loop that has continued for nearly a year and a half. Lavender and tea tree are just two of the essential oils that folks come to the NIEHS website to learn about.
What about 5G?
Another hot topic is 5G cell phone technology. In January 2020, an interview with NIEHS toxicologist Michael Wyde, Ph.D., about potential health effects of 5G cell phone technology, grabbed a lot of attention — and continues to.
In “NTP scientist weighs in on 5G technology,” Wyde explained differences between the various generations of cell phone frequencies. As use of 5G technology grows across the United States, people are naturally eager to learn about potential health effects of cell phone radio frequency radiation. Because health effects of 5G are yet unclear, Wyde described upcoming studies to look for effects in exposed rodents.
The most popular articles in 2020, regardless of when they were published, are listed below. Five appeared in 2019, suggesting sustained interest in their topics.
